Issues and Insights Vol. 14, No. 16 – Respond and Restrain: Deterrence and Reassurance in Northeast Asia

The US extended deterrent in Northeast Asia is strong. US alliances with Japan and South Korea are each arguably in the best shape in years, with alliance modernization efforts proceeding in tandem with domestic adjustments to security policy that strengthen the foundation for cooperative action. Policy toward North Korea, historically a wedge between Washington and allied governments in the region, is largely aligned, and serving as a glue rather than a source of discord.

This otherwise sunny outlook is darkened by the difficulties in the Seoul-Tokyo relationship. The (from a US perspective) obvious convergence of interests among the three governments is overshadowed by a lengthy and depressingly well-rehearsed list of problems. The second US-ROK-Japan Trilateral Extended Deterrence Dialogue, hosted by Pacific Forum and the Asan Institute for Policy Studies, with indirect support from the Project on Advanced Systems and Concepts for Countering WMD (PASCC) and the Defense Threat Reduction Agency (DTRA), explored ways to overcome those obstacles to enhanced cooperation. In an attempt to push the envelope, the 43 senior participants from the three countries joined 17 Pacific Forum Young Leaders (all attending in their private capacities) in discussions and a tabletop exercise that was designed to explore reactions to a nuclear contingency on the Korean Peninsula. The results were sobering and underscored the need for increased coordination and planning among the three governments to prepare for such a crisis in Northeast Asia.
